IC design Team Lead for Large Scale Quantum Collaboration with BOSCH. The project aims at developing a transmitter at 2.87GHz for diamond qubits in TSMC 40nm. A custom integrated circuit based Quantum Magnetometer. A 2nT/√Hz magnetometer was developed using a custom microwave (MW) chip and a ∑∆ current readout chip fabricated in 130nm RF-SOI. A custom integrated circuit based EPR spectrometer. An EPR spectrometer was developed using a custom PLL based sensor in TSMC 40nm.

Design and schematic implementation of a 300Msps SAR ADC in 22nm FDSOI. Patent: Digital-Analog-Umsetzer mit in Reihe geschalteten Kapazitäten DE 10 2018 206 453 B3.

The work focused on the development of quantum sensors using custom designed ASICs. In the first phase, a custom PLL was fabricated and a EPR spectrometer was developed around it using FPGAs, magnets, LDOs and current sources. In the second phase, a transmitter chip and a current readout chip was fabricated. A quantum magnetometer was developed using these chips, FPGA, laser and optical components.
